oIL BURNER.

Application filed December 20, 1923. Serial No. 681,686.

To all whom t may concern.'

Beit known that I, MATTHIAS H. REIMERS, a citizen of the United States,and resident of Hoboken, in the county of Hudson and State of NewJersey, have invented oer-tain new and useful Improvements in OilBurners, of which `the following is a specification.

This invention is `an atomizing device for forming `a spray or mist ofliquid fuel by causing two jets or streams of the liquid fuel to flowthrough a passage in opposite directions to the outlet orifice where thetwo streams meet under pressure and emerge to form the spray. i I

@ne of the main objects of my invention is to facilitate the cleaning of-all of the passages and the reassembling of the parts in the properadjustment.

A further object is to so design the parts that the passages throughwhich the liquid flows to the outlet orifice may be opened for cleaning,0r the parts having said passage are replaced by substitute parts toproduce a flame of different shape or size.

A further object is to provide a construction in which the liquid isdelivered under pressure through the outlet orifice to form th-e mist orspray, or may be delivered through said orifice by the action of steam,compressed air, or other motive fluid, and without necessitating anychange in the liquid delivery passage ororifice presenting member.`

In the accompanying drawings:

Fig. 1 is a side elevation of a burner constructed in accordance with myinv'en` tion'.

Fig. 2 is a top plan view.

Fig. 3 is a face view. j

Figs. A and 5 are sections on the lines 4-11 and 5--5 respectively ofFig. 1, and Fig. 6 is a section on the line 6-6 of Fig. 2.

My improved burner includes a head or body member 10 adapted to beconnected in any suitable manner to a liquid fuel supply pipe 11. Thehead has a large central chamber within which is a surface presenting anannular groove which receives the liquid fuel at one point and deliversit through an outlet orifice at a diametrically opposite point. The fuelthus flows to 'the outlet orifice as twostreams or jets from the samesource and in opposite directions, meeting ymeeting headon at a pointdirectly `at the outlet orifice. The parts which form or present thesaid lannular groovel are so designed that when removed the groove isexposed throughout its entire length, and thus easily cleaned. In thespecic construction illustrated there is provided an annular member orring 124 which seats against a shoulder within the head, and has itsouter cylindrical surface snugly fitting the peripheral wall of thechamber. The annular member 12 is held in place by a centrally disposedmember or plug 13 which has a flange portion 14 seating against the faceof th-e annular member 12, a plug portion 15 snugly fitting within theannular member 12, `and a stem portion 16 projecting beyond the oppositeside of the head to receive the clamping nut 17. By removing this nuitthe central member 13 and the annular member 12 may be removed from thehead;

Two of the three members cooperate to formi an annular groove. As shownthis groove 18 is formed on` the inner cylindrical face of the annularmember 12, and the inner or open side of the groove is closed by theperipheral surface of the plug portion 15."

The head 1() and annular member 12 have registering passages 19 leadingfrom the supply pipe 11 to the groove 18 to form an inlet or supplypassage to the groove. At a point diametrically opposite to this passage19 the annular member` is provided with an outlet orifice in the form ofa slot 20 cut in the peripheral face and intersecting the groove. Thehead is so designed that this slot 2Ol opensl directly into the air andforms the outlet orifice from the groove 18.` As shown the headhas aVshaped groove 21 in the face `thereof registering with the slot 20, andto permit the fuel to emerge from the slot 2O in the forml of asubstantially flat. fan-shaped mist. The mist or spraying effect isproduced by the two streams flowing along the groove 18 is oppositedirections from the passage 19` and opposite `to the slot or outletorifice 20.

It will be noted that by merely removing' the nut 17 the members 12and`13 may be removed and a new member 12 inserted with a larger orsmaller groove, and with the desired shape and size of slot 20 or otheroutletorice in accordance with the shape and character of the flame tobe produced. The removal of these-partsexposes v the inner sideof thegroove throughout its entire length, and permits it to be effectivelycleaned vvvhen necessary.

'In''assembling the parts itis essential thaty `the annular member v12be in a definite and predetermined position, particularly 'sofar asregards the slotl 2()y and the inlet passage 19. ny suitable registeringmeans may be employed, that shown being a pin 222 entendtion VAisparticularlyadaptedfor use offsteam,

compresse-d air, or atomizing fluidas fthe meansfor'formin-g the spray.Thisfmay be V acf joinplished .by 'providing the c entep lnember 131Withan aXial pa ssage pr chamber 23 communicating at one'end of the memberwith asupi'plypifpe 24.
